Sour Cream Coffee Cake

My favorite Sour Cream Coffee Cake is so moist and buttery, with a cinnamon streusel layer in the middle and on top, and drizzled with a sweet glaze.

Ingredients

STREUSEL

  • 1 3/4 cups all purpose flour
  • 1 cup packed light brown sugar
  • 1 1/4 tsp ground cinnamon
  • 1/4 tsp kosher salt
  • 3/4 cup (1 1/2 sticks) unsalted butter (COLD) cut into small pieces

CAKE

  • 1/2 cup unsalted butter softened to room temperature
  • 2 cups all purpose flour
  • 1 1/4 tsp baking powder
  • 1/2 tsp baking soda
  • 1/2 tsp kosher salt
  • 1 cup granulated sugar
  • 2 large eggs
  • 1 1/2 tsp vanilla extract
  • 1 cup sour cream

GLAZE

  • 1 cup powdered sugar
  • 2 Tbsp whole milk

Instructions

  • Preheat the oven to 350°F. Butter a 9x9 baking pan and set aside.

STREUSEL

  • To a small mixing bowl, add the flour, sugar, cinnamon, salt and butter. Using a pastry cutter, fork, or your hands, mix until it forms pea-sized clumps. Refrigerate.

CAKE

  • To a small mixing bowl, add dry ingredients (flour, baking powder, baking soda and salt), and whisk to combine. Set aside for now.
  • In large bowl, beat together the butter and sugar until fluffy. Beat in one egg at a time. Beat in vanilla extract.
  • Add 1/3 of the flour mixture. Beat together. Add in 1/3 of the sour cream. Beat together. Continue these steps two more times until everything is incorporated and blended well. 
  • Add half the cake batter to prepared pan, spreading evenly. Add half the refrigerated streusel, spreading in an even layer.
  • Top with remaining cake batter, then last half of the streusel on top.
  • Bake for about 55 minutes. The top should be golden brown and when a toothpick is inserted into the center, it should come out clean or with a few moist crumbs.
  • Remove from oven and let cool on wire rack.

GLAZE

  • While your cake cools, make your glaze by whisking together the milk and sugar. 
  • Drizzle with desired amount of glaze and enjoy.

Notes

  1. Recipe has only been tested using full-fat dairy products.
  2. When spreading cake batter over the streusel, I find it easiest to drop by the spoonful, then use an offset spatula to gently spread.
